{{As of|2024|January}}, two methane-fueled rockets have reached orbit. Several others are in development and two orbital launch attempts failed:
* [[Zhuque-2]] successfully reached orbit on its second flight on 12 July 2023, becoming the first methane-fueled rocket to do so.<ref>{{Cite web |last=Bell |first=Adrian |date=12 July 2023 |title=LandSpace claims win in the methane race to orbit via second ZhuQue-2 launch |url=https://www.nasaspaceflight.com/2023/07/zhuque-2-launch2/ |access-date=12 July 2023 |website=[[NASASpaceFlight.com]]}}</ref> It had failed to reach orbit on its maiden flight on 14 December 2022. The rocket, developed by [[LandSpace]], uses the [[TQ-12]] engine.
* [[Vulcan Centaur]] successfully reached orbit on its first try, called Cert-1, on 8 January 2024.<ref>{{Cite web |author1=Josh Dinner |date=2024-01-08 |title=ULA's Vulcan rocket launches private US moon lander, 1st since Apollo, and human remains in debut flight |url=https://www.space.com/ula-vulcan-centaur-first-launch-peregrine-celestis-moon-mission |access-date=2024-01-08 |website=Space.com |language=en}}</ref> The rocket, developed by [[United Launch Alliance]], uses the [[Blue Origin|Blue Origin's]] [[BE-4]] engine, though the second stage uses the hydrolox [[RL10]].
* [[Terran 1]] had a failed orbital launch attempt on its maiden flight on 22 March 2023. The rocket, developed by [[Relativity Space]], uses the [[Aeon 1]] engine.
* [[SpaceX Starship|Starship]] achieved a [[transatmospheric orbit]] on its [[IFT-3|third flight]] on 14 March 2024,<ref>{{cite web |title=Starship's Third Flight Test |url=https://www.spacex.com/launches/mission/?missionId=starship-flight-3 |access-date=2024-05-07 |website=SpaceX }}</ref> after two failed attempts. The rocket, developed by [[SpaceX]], uses the [[SpaceX Raptor|Raptor]] engine.

Blue Origin developed the BE-4 LOX/LNG engine for their [[New Glenn]] and the United Launch Alliance Vulcan Centaur. The BE-4 will provide 2,400 kN (550,000 lbf) of thrust. Two flight engines had been delivered to ULA by mid 2023.
In July 2014, [[Firefly Space Systems]] announced plans to use methane fuel for their small satellite launch vehicle, [[Firefly Space Systems#Firefly Alpha|Firefly Alpha]] with an [[aerospike engine]] design.<ref>{{cite web |title=Firefly α |website=Firefly Space Systems |access-date=5 October 2014 |url=http://www.fireflyspace.com/vehicles/firefly-a |url-status=dead |archive-url=https://web.archive.org/web/20141006064518/http://www.fireflyspace.com/vehicles/firefly-a |archive-date=6 October 2014}}</ref>
